Abstract
The utility model discloses a cross facula location whiteboard, blank main part and laser pen including the rectangle, the photosensitive sensor array has been arranged respectively to blank main part four sides, the laser pen jets out cross light to the blank main part, cross light is the infrared ray, the laser pen still jets out visible luminous point to the blank main part, it is thus clear that the luminous point is 1~2mm with the interval of cross cross -over. The utility model discloses an infrared cross light location to it is thus clear that the intersect of cross light is indicateed to the luminous point, not only directly perceived but also do not influence the display effect of screen, it is very convenient.
Description
Technical field
This utility model is related to electronic whiteboard field, and in particular to a kind of cross spot location electronic whiteboard.
Background technology
Many people had following experience computer desktop to be shown to the occasion demonstrated in projection screen：During demonstrator
Before projection screen by laser pen indicate explain, when and to before computer operate mouse demonstration.Its reason is laser pen and computer
Without interaction, it is impossible to realize the function of mouse.
There is one kind that shooting is carried out to projection screen by photographic head at present and obtain video flowing, and carry out image procossing identification and swash
Light pen hot spot, then the system that the function of realizing mouse is interacted with computer, its significantly limit including：First, real-time：Processing speed
The upper limit cannot break through the frame rate of photographic head；2nd, robustness：Extreme case be unsatisfactory for image procossing it is assumed that causing algorithm
Failure；3rd, integration：In legacy system, photographic head is necessarily mounted at ad-hoc location, and the change that takes up room is big, or needs extra
Demarcating steps, operation difficulty become big.
Also a kind of method for realizing wireless mouse with laser straight line, using a level, a vertical laser straight line
One coordinate system of composition, with reference to an X to the laser receiver that miniature laser induction apparatuss are equipped with Y directions, composition one
It is individual can be remote, pinpoint wireless mouse system, without the need for contact screen, it is possible to reach the purpose of long distance positioning.
If but laser straight line adopts visible ray, clearly cross hot spot will be shown on screen, Showing Effectiveness On Screen is affected, such as
Fruit adopts infrared light, then be not directly visible the cross point of cross hot spot, although mouse can hover over the infall, but when the back of the body
When scape is less with mouse aberration, observation is relatively more painstaking, and operation difficulty is than larger.
The content of the invention
The technical problems to be solved in the utility model is to provide a kind of cross spot location electronic whiteboard, can solve existing
Technology laser straight line realizes wireless mouse, will affect display effect according to visible ray, can then increase behaviour according to infrared light
Make difficulty.
This utility model is achieved through the following technical solutions：
A kind of cross spot location electronic whiteboard, including the blank main body and laser pen of rectangle, four side of blank main body
Light sensor arrays is arranged with respectively, and the laser pen projects cross light to blank main body, and the cross light is infrared
Line, the laser pen also project visible point of light to blank main body, and the spacing of the visible point of light and cross cross-over is 1 ~
2mm。
Further scheme of the present utility model is that the visible point of light is sent by color-adjustable LED, is set on the laser pen
It is equipped with toning knob.
This utility model advantage compared with prior art is：
First, positioned using infrared cross light, the cross point of cross light is indicated with visible point of light, it is not only directly perceived but also do not affect
The display effect of screen, it is very convenient；
2nd, visible point of light is sent using color-adjustable LED, knob adjusts visible ray according to background or hobby by mixing colours
Point color, adapts to different demands.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
A kind of cross spot location electronic whiteboard as shown in Figure 1, including the blank main body 1 and laser pen 2 of rectangle, it is described
1 four side of blank main body is arranged with light sensor arrays 3 respectively, and the laser pen 2 projects cross light 4, institute to blank main body 1
It is infrared ray to state cross light 4, and the laser pen 2 is also to the injection visible point of light 5 of blank main body 1, the visible point of light 5 and cross
The spacing in 4 cross point of light is 1 ~ 2mm, and the visible point of light 5 sent by color-adjustable LED, and tune is provided with the laser pen 2
Color knob 6.
Claims (2)
1. a kind of blank main body of cross spot location electronic whiteboard, including rectangle（1）And laser pen（2）, the blank main body
（1）Four sides are arranged with light sensor arrays respectively（3）, the laser pen（2）To blank main body（1）Project cross light（4）,
